arséniure de cobalt et de nickel

CONT: Au Maroc et dans quelques autres pays, les gisements à teneur élevée en arséniure de nickel et de cobalt fournissent une quantité appréciable de cobalt.

CONT: ... nickel-cobalt arsenide could potentially be found in the Paloehelikian granitoid rocks ...
CONT: A specimen of native silver ore from the Bullard's Peak district, New Mexico, ... shows native silver associated with a cobalt-nickel arsenide.
CONT: Continuously sampled intervals in this alteration zone include 0.38% Co, 0.68% Ni and 0.99% As over 8.5 m between 37.0 and 45.5 m, and 0.35% Co, 1.09% Ni and 1.18% As between 43.5 and 45.0 m. Similar concentrations of these elements, indicative of nickel-cobalt arsenide minerals, are spatially associated with uranium mineralization at deposits such as West Bear and Key Lake.
